The history of preserved eggs
According to legend, during the Taichang period of the Ming Dynasty, the owner of a small teahouse in Wujiang County, Jiangsu Province knew how to do business, so the business was booming. Due to the shortage of manpower, the shopkeeper poured the brewed tea into the ashes when entertaining guests. Coincidentally, the shopkeeper also keeps several ducks and loves to lay eggs in the ashes. When the host picks up the egg, it is inevitable that there will be omissions. Once, the shopkeeper found a lot of duck eggs while cleaning the tea residue from the furnace ash. He thought they were inedible. Who knows, when I peeled it off, it was dark and bright, with white patterns on it. When you smell it, a special smell comes to your nose. Have a taste. It's fresh, smooth and refreshing. This is the most primitive preserved egg. Later, after continuous exploration and improvement, the production technology of preserved eggs was improved day by day. On the other hand, preserved eggs originated in Tianjin. Word of mouth: About 200 years ago, a son of a wealthy family in a village in Tianjin made a coffin for his mother and put it in an empty house for later use. After a long time, when his mother was still alive, he ordered his family to sprinkle lime and plant ash into the coffin to prevent moisture, and left a big gap on the coffin lid for ventilation. Forget it when it's over. The following year, when her mother died, she moved the coffin to the grave and found more than 100 eggs in plant ash. The dutiful son was so angry that he took it out and dried it. The shell is broken, and the inside becomes a dark brown transparent crystal, which is very chaotic. Someone who dares to taste it is really delicious. The onlookers also felt strange, so they quickly tasted it, and the result was like this. People of insight will follow suit afterwards, putting fresh eggs in lime and plant ash, and so on. As a result, neighbors followed suit and called them "color-changing eggs". For a long time, this original technology has been circulated in Jiangsu and Zhejiang provinces, and it has been improved repeatedly and perfected day by day. As a brand-new food, color-changing eggs have been pushed to the market by Jiangsu and Zhejiang people who are good at business. So today's "preserved eggs in Songhua" began in Tianjin and became in Jiangsu and Zhejiang.
No matter what legend preserved eggs come from, they are later than ice cream.
Cheese was not invented by China, but it has a longer history.
There is a legend about the origin of cheese: five thousand years ago, a businessman accidentally invented cheese while crossing the desert. He used a bag made of sheep's stomach to transport milk, which reacted with the natural stomach membrane under constant bumps to form cheese. This legend may be true. Cheese has been mentioned in the Old Testament, dating back to about 3,500 years ago.
In 1 century, the Roman historian Pliny the elder first mentioned Swiss cheese, calling it "Caseus Helveticus", which means "the first Swiss cheese".
Caviar also has a long history, but it was not invented in China.
For more than 2000 years, caviar has been highly praised by the world. Aristotle wrote a note about it in the 4th century BC.
